ASP。NET文本框在回发后通过javascript在客户端更改值时丢失值

我正在通过javascript客户端设置文本框的值。当我刷新页面时,该值丢失。

我已经阅读了将值放在隐藏字段中的建议,我不想这样做。这看起来像是黑客。

文本框位于用户控件中,如下所示:

<div id="Row" class="RaidRow" runat="server">
    <asp:Button ID="RaidRowButton" runat="server" CssClass="RaidRowButton" OnClick="RaidRowButton_Click" />
    <asp:TextBox ID="CharacterNameTextBox" runat="server" CssClass="RaidRowControl SlotTextBox" MaxLength="12" />
    <asp:Label ID="ClassNameLabel" runat="server" CssClass="RaidRowControl ClassLabel" />
</div>

此控件位于.aspx页面上。

function VerifyCharacter(slotNumber, event)
{
    var enterWasPressed = false;

    if (event && event.which == 13)
    {
        enterWasPressed = true;
    }
    else if (window.event && window.event.keyCode == 13)
    {
        enterWasPressed = true;
    }

    if (event == null || enterWasPressed)
    {
        var realmName = 'Lightninghoof';

        var characterNameTextBox = GetCharacterNameTextBox(slotNumber);
        characterNameTextBox.style.color = '#CCCCCC';

        var classLabel = GetClassNameLabel(slotNumber);
        classLabel.style.color = '#CCCCCC';
        classLabel.innerHTML = 'Unknown';

        WoW_Stats.CharacterInformation.GetCharacterInformation(realmName, characterNameTextBox.value, slotNumber, GetCharacterInformation_Success, GetCharacterInformation_Failed);
    }
}

web服务调用完成后,将调用以下javascript函数:

function GetCharacterInformation_Success(characterInformationResult)
{
    var characterInfo = Sys.Serialization.JavaScriptSerializer.deserialize(characterInformationResult, true);

    var classLabel = GetClassNameLabel(characterInfo.SlotNumber);
    classLabel.style.color = characterInfo.ClassColor;
    classLabel.innerHTML = characterInfo.ClassName;

    var characterNameTextBox = GetCharacterNameTextBox(characterInfo.SlotNumber);
    characterNameTextBox.style.color = characterInfo.ClassColor;
}
